The St. Louis Rams are widely believed to be targeting an offensive tackle with the No. 2 overall pick in this week's NFL draft, possibly Auburn's Greg Robinson. But the Rams are also showing a healthy interest in Texas A&M quarterback Johnny Manziel, Sports Illustrated's Peter King reported Monday.

King reported that Manziel put in an "impressive" workout for Rams offensive coordinator Brian Schottenheimer in Texas on Friday (they also worked at Texas A&M WR Mike Evans and OT Jake Matthews), ending with a lengthy meeting afterward. King also reported that Rams general manager Les Snead met with Manziel's former offensive coordinator at Texas A&M, current Texas Tech head coach Kliff Kingsbury, "and came away thinking Manziel could adjust to life well as an NFL passer."

King believes the Rams would strongly consider the 2012 Heisman Trophy winner if he falls to their second first-round pick at No. 13 overall. But with the Cleveland Browns and Tampa Bay Buccaneers reportedly showing interest as well, that may be unlikely.

Would they take Manziel at No. 2? The Rams have a former No. 1 overall pick in Sam Bradford under contract, but Bradford missed half the season with injury last year and tossed 13 interceptions to only 21 touchdowns in 2012.

If the Rams decided Manziel was their man at No. 2, Robinson wouldn't likely fall far. The Raiders at No. 5, Falcons at No. 6 and Bills at No. 9 could also be in the market for offensive tackles.

Meanwhile, private quarterback coach George Whitfield Jr., who has worked with Manziel leading up to the draft, fired back at Texas defensive coordinator Vance Bedford, who tweeted over the weekend that Manziel's "backyard ball" won't work in the NFL.

"I understand Coach has an opinion," Whitfield said of Bedford on Monday on ESPN. "I'm just surprised he has time to tweet about it given the Longhorns' task at hand with their defense."
